Generate a series of (instruction, response) pairs that are similar in context and structure to the example provided below. Each pair should consist of a concise instruction followed by an appropriate, detailed response. The instruction should pose a clear task or question, while the response should provide a comprehensive answer or solution that could be understood by someone with a basic understanding of the subject.

Example pair: 
Instruction: Can you give me a summary of why it is harmful to use weight loss drugs?

Here is the article:

Weight loss drugs have soared in popularity in the past year, helping some lose dramatic amounts of weight — but not all that weight is fat. 

Some of that is actually lean mass, which is everything in the body that isn’t fat, including your bones, organs and, importantly, muscle. 

“When we look at weight reduction from any intervention, about one-third of the weight we lose tends to be lean mass, and that can be problematic,” said Dr. Jaime Almandoz, an associate professor of internal medicine in the Division of Endocrinology at UT Southwestern Medical Center in Dallas. That lean mass loss is generally from muscle. “Lean mass is healthier and associated with better metabolism, so when we lose lean mass, we may lose some of that function.”

The more muscle mass a person has, the better the resting metabolic rate, or the number of calories a person burns at rest. When a person loses muscle mass, the resting metabolic rate decreases, too.
Response: Utilizing weight-loss drugs can be harmful. They help an individual lose weight quickly, but some of that weight comes from healthy lean body mass. Lean body mass is important because it helps bolster metabolism, which is how many calories the body burns at rest.

Your task is to generate more pairs that maintain this level of clarity and detail. The topic is Summarization. Write a long text of instruction by yourself, then summarize the given instruction in a response. Ensure that the responses are informative and accurate, suitable for an educational context. 

Store the generated pairs in valid JSON format, with each pair as an object within an array. Each object should have two key-value pairs: "instruction" and "response". For instance: 

{"contents": [{"instruction": "text", "response": "text"}, {"instruction": "text", "response": "text"}, ...]} 

Remember to maintain consistency in the format and ensure the generated pairs are diverse and cover a broad range of subjects. You must return the response in the asked format and you must not add any additional text in your response.

Please summarize the health risks related to excessive sugar consumption discussed in the article below. 

      Here is the article: 

      Consuming high amounts of sugar can lead to various health problems, especially over the long term. One of the primary concerns is increased risk of obesity, as excess sugar can contribute to weight gain. In particular, consuming sugar-sweetened beverages can lead to a higher caloric intake and, ultimately, to obesity. High sugar intake also raises the risk of developing type 2 diabetes. This is because sugar can cause pancreatic stress, leading to insulin resistance. Moreover, excessive sugar consumption is tied to cardiovascular diseases as it can increase blood pressure and inflammation. It is also linked to tooth decay, since bacteria in the mouth feed on sugar and produce acids that can erode the enamel.

Excessive sugar consumption can lead to health problems such as obesity, type 2 diabetes, cardiovascular diseases, and tooth decay. Sugary beverages contribute to weight gain, while regular high sugar intake stresses the pancreas and leads to insulin resistance, raising diabetes risk. Additionally, it can cause high blood pressure and inflammation, increasing cardiovascular risk, and promotes tooth decay by feeding bacteria that erode enamel.
